Is Hydrocodone Safe for Cats?
Why it’s a problem
Cats react intensely to opioids, and hydrocodone exposure has been reported to cause profound sedation, pinpoint pupils, and slowed breathing in cats. A single human tablet can exceed a tolerable feline exposure. Combination cough or pain products may contain additional ingredients, such as acetaminophen, that are especially poisonous to cats.
How to keep your pet safe
Keep hydrocodone in any form — tablets, syrups, or combination products — in closed storage away from cats. Cough or pain treatment for a cat should come only from a veterinarian.
Warning signs to watch for
Profound drowsiness, wobbliness, pinpoint pupils, drooling, slow or shallow breathing, low body temperature; severe cases: unresponsiveness, collapse.
When to call the vet
Call your veterinarian or a pet poison hotline immediately and describe the exact product, including combination ingredients. Cats with opioid exposure may need monitoring until breathing is stable.
Common questions
My cat ate one of my hydrocodone tablets — will she be fine?
Not something to assume — a single tablet can dangerously sedate a cat and slow breathing. Call your vet or a pet poison hotline immediately.
Why is acetaminophen in some hydrocodone products a problem for cats?
Cats cannot process acetaminophen, and it destroys their red blood cells even in small amounts. Always report combination products when you call for help.
